When I first started I bought two of the Mars Hydro 600 orginal series , they work okay right now they're sitting at the local Hydro shop on consignment good advice get a good light, not saying the one you're looking at isn't a good light do your research before you spend your money the moral to the story is don't do what I did buy lights and then buy more lights and then buy more lights. Currently running 2 315 CMH one 400w HPS loving every minute of it.
